Abstract
Methods and systems for assessing characteristics of a lung of a patient. A method includes, during an applied positive end expiratory pressure, identifying a first position of a patient, acquiring first impedance data representative of at least a region of patient's lung when the patient is in the first position, during the applied positive end expiratory pressure, identifying a second different position of a patient, acquiring second impedance data representative of at least the region of patient's lung when the patient is in the second position, comparing the first impedance data with the second impedance data, and determining whether the applied positive end expiratory pressure is sufficient to effectuate recruitment.
Claims19
A method for assessing a characteristic of a lung of a patient, the method comprising:
- applying and maintaining a constant positive end expiratory pressure between 0 and 40cmH2O to the patient with a ventilator system;
- during the constant positive end expiratory pressure, identifying a first position of the patient;
- during the constant positive end expiratory pressure, acquiring first impedance data representative of at least one region of the patient's lung comprising a portion of the lung less than the entire lung when the patient is in the first position;
- during the constant positive end expiratory pressure, identifying a second different position of the patient;
- during the constant positive end expiratory pressure, acquiring second impedance data representative of the at least one region of the patient's lung when the patient is in the second position;
- comparing the first impedance data with the second impedance data to identify a change in a characteristic of the patient's lung;
- determining that the patient has returned to the first position;
- acquiring third impedance data of the at least one region of the patient's lung, the third impedance data reflecting the first position of the patient;
- and
- comparing the first impedance data with the third impedance data to determine whether the applied constant positive end expiratory pressure is sufficient to effectuate or sustain recruitment.
